Without calculating any wavelength values, predict which of the following electron transitions in the hydrogen atom is associated with radiation having the shortest wavelength.  a. from n=1 to n=2 b. from n=2 to n=3 c. from n=3 to n=4 d. from n=4 to n=5

Which transition of an electron in the hydrogen atom emits a photon with the smallest amount of energy?  a. n = 6 to n = 1 b. n = 7 to n = 1 c. n = 2 to n = 1 d. n = 7 to n = 6 e. n = 1 to n = 7

Suppose the Death Star's laser in Star Wars uses green light at a wavelength of 541.4 nm. A. Calculate the energy in J/mol of this light (i.e. the energy of a mole of photons). B. If the green light is emitted by an electronic transition to n = 4 in the He* ion, what is the initial energy level? Remember that for non-hydrogen atoms, the Rydberg constant is multiplied by a factor of Z2, where Z is the atomic number of the element (i.e. RH*Z?).
